Two gems of SBB Historic at Erstfeld depot, the iconic Gotthard locomotives Ae 6/6 # 11402 "URI" and # 11411 "ZUG" side by side. # 11402 is one of two prototypes, built in 1951 by SLM, BBC and MFO and taken over by the SBB in 1953, with 4426 kW. It is maintained and operated by the Historic Team Erstfeld nowadays. # 11411 is from the first series order and was delivered in 1956, with a more powerful electric brake. It is part of the core fleet of SBB Historic.
